The potential of hydrogen for decarbonising steel production

the steel sector can lead to synergies with decarbonisation efforts in other sectors such as transport (hydrogen -powered trains, trucks, cars, ships, airplanes), heating (e.g. replacing natural gas), and industrial processes such as ammonia produ ction. • Higher steel prices would dampen the demand for steel in many other sectors of the

Steel Deoxidation: Part One :: Total Materia Article

Steel Deoxidation: Part One. Abstract: Deoxidation is the removal of excess oxygen from molten metal. The procedure involves adding materials with a high affinity for oxygen, the oxides of which are either gaseous or readily form slags. The deoxidation of steel is usually performed by adding Mn, Si and Al, or rarely by adding Cr, V, Ti, Zr and B.
